RAIL JACK.

To all whom, it magy concern:

Be it known that I, FREDERICK HAcH- MANN, a citizen of the United States, and resident of the cit of St. Louis and State of Missouri, have invented certain new and useful Improvements in Rail Jacks, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereqf.

y invention relates to .certain new and useful improvements in rail jacks, and has for its primary object the construction of a jack for moving and alining railway rails, the primary object of which is to construct a jack with a strong fulcrum or pivotal connection between the base and lever; and further, to provide such a connection between the lever and base that the entire device may be carried by the handle without any danger of the base being separated from the lever.

In the drawings,

Fig. 1 is a side elevation of my 1mproved jack, showing the device adJusted so as to be inserted. under the ball of a railway rail;

Fig. 2 is a section taken on the line 2 2 of Fig. 3, looking in the direction of the arrows, the application of the Jack to the ball of a railway rail being shown in dotted lines Fig. 3 is a front view with the handle and lever in an elevated position;

Referrin tothe drawings:

4 indica es the base or support which is preferably cast and formed on the under surface thereof are prongs 5 which are intended yto prevent the jack from slipping when in use. The base or support 4 is rovided with upstanding side portions 6 w ich are connected by means of a web 7. rlFhe' web 7 is substantially vertical, except the upper portion 8, which inclines in a forward direction. Formed in each of the upstanding side portions 6 are circular bearings 9, and rearwardly inclined slot-s or openings 10 which lead into said bearings. Formed in the forward projecting portion `8 is a curved bearing 11 having the same deree of curvature as the bearings 9. rlhe earings 9 in each of the upstanding portions 6 and the bearing 11 form a continuous bearing throughout the width of the support. 12 indicates a lever which has a hollow portion 13 into`which a handle 111 is inserted. The portion 13 is provided with a shoulder 15 which is adapted to engage the ball pf the rail, as illustrated in dotted lines in Fig. 2. Formed forward of the shoulder 15 are a series of smaller shoulders 16, 17, and 18. The shoulders 15 and' 16 are especially designed to engage with the ball of the rail in the operation of the device.

In the operation of the device, should the shoulders 15 become disengaged with the ball of the rail, the ball will catch on the shoulder 16 and tend to move the rail further. The shoulders or ribs 17 and 18 are designedto engage the web of the rail. The shoulders 16 and 17 are intersected by grooves 19 which have a tendency to prevent the lever from slipping latterly on the web. Formed inte al with the lever is a semicircular bearing 20, the ends of which project beyond the lever and has flattened faces 21. These flattened portions are of the width of the inclined slots 10.

In assembling the lever with the base or support, the lever 12 is adjusted in position so that the flattened into the o enings 10. In order to remove the lever rom the base or support, the lever must be adjusted so that the flattened portions may be removed through these inclined s ots.

It will be seen from this construction that the entire jack may be carried by the handle. as illustrated in Fig. 1, and the support will not become detached from the lever.

When my device is in operation, (see Fig. 2 for illustration) it willbe observed that the entire lifting strain will be rst received by the semi-circular bearing 20, and will be transmitted against the forwardly inclined portion 8, and thence to the web 7 the web 7 being strengthened by the side portions 6. Thus it will be seen that l provide a very strong and serviceable jack capable of standin any strain encountered in alining or straig tening tracks.

Having fully described my invention, what l claim is:

1. A jack comprising a support havin a substantially vertical web, a semi-circu ar portions will pass.

bearing formed throughout the web, said bearing being provided with rearwardly inclined slots, a lever provided with a semicircular integral bearmg adapted to be seated on the bearing formed in theweb, and a series of transverse shoulders formed on the forward end of said lever, certain of said shoulders being adapted to'engage beneath the ball of a rail, and the others toI engage the web thereof.

2. A jack comprising a base having vertical extending side walls, a web formed integral and between said walls, a semi-circular bearing formed in the walls and the web,l said walls being provided with rearwardly inclined slots, a lever provided with a semicircular bearing and flattened terminal portions arranged to pass through said slots, said lever being provided on its forward and upper surface with a series of transverse shoulders, certain of which are arranged to engage the ball of the rail, and the others, the web thereof; l

3. A jack comprising a base havingside walls, a web formed between and integral with said side walls and having an u per portion extending forwardly at an ang e to said web, said forwardly extending portion and the side walls being provided with a semi-circular bearing, there being rearwardly inclined slots formed in the side walls, a lever having a hollow portion Vadapted to receive a handle, and having a forward portion provided with a series of 'transverse shoulders, a semi-cylindrical portion formed integral with said lever and provided with flattened end portions adapted to be passed through the inclined slots formed in the side portions.

In testimony whereof, I have signed my name to this specification.

FREDERICK HACHMANN.
